Chemical disposal

[linotas]

Can anyone tell me how they dispose of Iron Sulphate solution? In small quantities I just wash down the sink (into our chemical sump) but I have a litre at once to get rid of.

Also waste copper chloride solid?

Thanks in advance

Perhaps small amounts of Iron Sulfate each day.
Copper Chloride solid, can go to the bin, wrap in newpaper etc.

I use sodium carbonate, stand to precipitate, then decant the solution and wrap the solid and bin it.

If your local tip has an EPA recycling shed, you can take waste chemicals there and they will be recycled.
